  1. A different car ! 5 Star Review

    Posted by on 8th Mar 2017

    We just finished my gt4 upgrades. Shark Werks gears, GT limited slip diff., Cobb tune and Fabspeed headers. The car is now i think as it should be ! The gearing is fabulous on the street(no track time yet). You actually get to shift gears. The diff is amazing ! The exhaust with Fabspeed headers and factory muffler sounds great !


  2. God of Thunder! 5 Star Review

    Posted by on 28th Dec 2015

    I recently installed the Fabspeed Race Headers and Valvetronic Exhaust System on my Porsche GT4...or should I say, I recently came face to face with The God of Thunder. For me, the sound of a car is nearly paramount in the car experience. The GT4 with this Fabspeed setup is better than anything I have ever heard. Even beats my favorites of a screaming Ferrari V12, the Lexus LFA, the Porsche Carrera GT, and the
    C7 LeMans Corvette. I would take this over any of those...and I don't say that lightly.

    The setup I chose is not for the faint of heart. 7500 rpms with open windows in a tunnel would make Zeus himself cower. Kudos to Fabspeed and Porsche for attaining automotive perfection.

NOTE: The Cayman GT4 Race Headers do not include catalytic converters, and are recommended for track/off-road use only. In most vehicles, removing the catalytic converters may trigger a Check Engine Light.  HOWEVER, in over 200 miles of testing, our development vehicle did NOT trigger a CEL with these Race Headers installed.

This product is or contains a Racing Cat Bypass Pipe, which will give you check engine lights on OBD2 cars. We suggest pairing this product with racing software to prevent fault codes and check engine lights. Racing Cat Bypass Pipes are solely intended for track and race cars as they are NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation.
